SPECIFICATION forming part. of Letters Patent No. 333,997, dated January 12, 1886.

Application filed April 18, 1885. Serial No. 162,643. (No model.)

To (ZZZ whom it may concern:

Be it known that I, JOHN DAVIS, of Providence, in the State of Rhode Island, have invented a new and useful Bobbin-Holder for Spindles of Spinning-Machines; andI do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereo t'.

Figure l is a view of the spindle with bobbin and fastener. Figs. 2 and 3 are enlarged portions of spindle and bobbins, showing different views of the fastener. Fig. 4 is a face or top view of the fastener removed. Fig. 5 is a portion of the spindle with the fastener attached, but omitting the prongs.

The object of my invention is to hold the bobbin rigidly in its perpendicular position upon the spindle without the aid of packing, and to save the stock now used for such packing; and it consists of a fiat metallic disk surrounding and attached to the spindle, and pro vided with springs and spurs extending upward to receive and hold the bobbin in place.

In my invention I take a metallic plate of the proper size and shape and strike it up into the form of the fastener A, as shown in Figs. 2, 3, and 4, after which a hole is punched therein large enough to permit it to be moved downward upon the spindle E until it reaches its proper position, when it is secured.

The spring-arms B B of the fastener are so curved that they will be forced apart by a gentle downward pressure of the bobbin F, to admit the head thereof, and will readily adapt themselves to the annular groove therein, as shown in Figs. 2 and 3, and thus hold the bobbin in a rigid position.

To provide against the slipping of the bobbin, I cut the sides of the plate so as to form a sharp point, 0 0, upon each side, which is turned upward, forming spurs, which enter the head of the bobbin as it is forced down and prevent it from turning upon its spindle. These are not absolutely necessary to my invention, but go to insure the best result.

A piece of rawhide, D, may be placed upon the spindle before the fastener, if desired, which will aid in supporting the plate, and also will furnish a surface against which the knife will strike without injury, which is used to cut away and remove the surplus yarn, which sometimes is wound below the bobbin.

What I claim as my invention, and desire to secure by Letters'P-atent, is-

A holder for bobbins, consisting of the part or plate having the prongs or points 0 0 and the spring-arms B, substantially as and for the purpose set forth.

JOHN DAVIS.
